Milwaukee PERFORMANCE+ Metal Grinding Wheel, 4-1/2" X 1/4" X 5/8"-11 Threaded - Type 27

Milwaukee PERFORMANCE+ Metal Grinding Wheel, 4-1/2" X 1/4" X 5/8"-11 Threaded - Type 27

The Milwaukee 49-94-0607 PERFORMANCE+ Metal Grinding Wheel is a heavy-duty Type 27 grinding wheel engineered for faster material removal, greater control, and extended wheel life in metal and stainless-steel applications. Built with premium zirconia grain and an enhanced bonding structure, this wheel continuously exposes fresh abrasive grain during use to maintain aggressive grinding performance and smoother operation. Its 5/8"-11 threaded hub arbor allows for quick, secure installation on compatible grinders without requiring additional arbor hardware. Reinforced with 3 sheets of high-strength fiberglass and a high zirconia grain concentration, it delivers up to 5X longer life than standard grinding wheels while powering through steel, angle iron, pipe, rebar, stainless steel, and nickel-based alloys like rough welds personally offended it.
